mounted'on a vshaft-31- e'xte'nding through the 'v shaft carrying thelsupport, which shaft may be rotated by means of a hand wheel 32 (Fig.1), to adjust the position of the blocks 23. After the?` hat` has beenplaced on the support, rotation of this hand wheel will move the blocks23 outwardly to expand the band to tightly hold the hat in position.TheV hatis released byl rotating the hand wheel in the oppositedirection.

The trimming mechanism for the brimis. mounted on a main slide 33 havingsuitable guiding means, such as grooves 3.4, in. its opposite edges toreceive suitable guides 35 carried'A vby the frame. 20, and mount-ed onthis slide is a support 36. TheV support is mounted. for a combinedreciprocating; and

rocking movement on the slide, and-A for this purpose the slide isprovided with'a longitudinal slot 37 (Fig.r 3), throughv which passes ascrew 38 threaded into' the bottom of the support. Thisscrew guides thesupport for reciprocating movement on the slide and it also forms apivot about which the support may be rockedy in theplane of the slide.The support 36 is provided with upwardly extendingbearing lugs 39" inwhich areV mountedl` the supportingl means for the jaws 40 and 41forming guidesA for the hat brim duri-ng the trimming. operation. Theouter jaw or guide 40 is stationary relative to the support- 36 and iscarried by a block 42 adjustably mounted in? the forked end of aE rod-43 by av suitable clamping'screw 44, the guide being mounted on a bolt45, as by means of clamping nuts 46, the bolt 45 being threaded into thelower endvof the block` 42, andthe rod 43 is adjustably se cured in thesplit end of a supporting element 47 by means of a clamping' screw 48,the element 47 being mountedV between the lugs 39 as by means of a screw49'.v The front or brim engaging surface of the guide 46)` is concaveboth vertically and horizontally, but vthe upper-- outside corners arecut away, as shown at 50, to gradually bend the brim into the spacebetween the guides, and also tov give a. gradual curve to its path ofexit ontheether side;

nCarried bythe guide 40 is a rotatable feeding wheel 51 which is mountedto rotate on the bolt 451andit has a concave annularl surface 52 whichprojects through an epening 53 at substantial-ly the center of thecurved surface of the'guide to engage the outer surface of the hat brim.This surface 52 .may be knurledl or roughened in any suitable manner soas to giveV a greater hold on the surface ofv the brim. In the bottom ofthis wheel is provided means for rotating it, ysuch as a' fibre rin-g54, and the wheel is inclined to the plane of the table or plate 2l andmounted so that this ring on one side of the .wheel Awill engage thesurface of the table. It will thus be clear that rotation the table willlrotate the -fee'd wheel through the friction-al engagement of thisfibre ring. The feed wheel coacts with the second guide 41 and is. so.proportioned that the surface engaging thev brim of the hat will moveslightly faster than the speed of the brim so that there is a slighttendency of the feed wheel to draw the brim between the guides. There isthus' no tendency of the friction of the guides` on the brim or theresistance of the cutting knife vto distort the brim.

The-inner orfopposite guide 41 is mounted so that it may be moved to andfrom the guiding position,` as shown*` in Figs` 5- and 6. It is carriedby a rod 55` adjustably mounted in thef split end 5,6 ofV a bar 5.7'y bymeans of a clamping screw 58, and this'bar is inl turn adjustablymounted in the split endl of Va supporting element 59 by means of aclamping screw 60, element 59- beingl pivotedr to the lugs 39 by, asuitable pinV 61. A suit-able spring isv provided tending to hold thisguide 41 in its elevated or ineffective position, as shown in Figs.' 3and4. A

lconvenient way of mounting this' spring is to provide a socket leadingVfrom the end of the rod 43: and mount therein a plunger 62 having al.rounded `outer' end 63 engaging the element 59, with a spring 64tend-ing to push this plunger outwardly and swing the element 59clockwise about its pivot, as viewed in Figs. 3, 4, 5 and 6i Thev freeedge 65 of the guide 41isA rounded as shown inV Fig. 15to engage theupper inner surface ofthe hat brim as it: passesbetween the guides, andit has a notch 66 on its upper side in which a trimming knife 67 swings.Th-isknife is `supported on a bar 68l pivoted at 69 to a block 70`adjustably secured on the' rod- 55, as by a set screw 71'. This bar 68is slit at its lower end,` as shown at 72, Fig. 13, and the knife isclampedin notches at the lower ends of these si es by means of a thumbscrew 73;- The knife preferably has an inclined cutting edge, as shownAin 15, and when projected! from the notch 66 into trimming;V position"7as showninv Fig. 6, the point thereof preferably7 rests against awoodenk block'74 set in a notch in the guide 40. 1

The bar 68 is providedV with a pin 75 on one side thereof extending.into an opening in one end of `a spring connecting rod 76. This rod is aflat rectangular bar which is adapted to yield laterally but tends tomove itsi free end toward the bar 68 to maintain its connection withthepin 75, and it is' pivotally connected at its opposite end, as shownat 77, toa lever 78 pivoted to one of the lugs 39 at'79. The rod76carries a cylinder 80l which is securedto the rod by suitable screws 81and this cylinder has a pocket leading from one end in which a plunger82 is mounted. They outer end 83 of this plunger is rounded and restsagainst r`one lof the lugs 39, and thespring 8,4v bearing againsttheother fend of vthe plunger poseineansv is provided which lowers theslabbed off at 88 to allow the element 59 to which this tends to forcethe knife 67` toits retracted 'l vpositionito pushfthe brimslig'htlylower,and`

Also pivoted between the lugsr39 backwardly ofthe'pivotedsupportingelement' 59 is a hand lever'85, its pivot-beingshown at 86, and this lever is providedfwith a:

'curved surface 87 arranged. to engagethe 'element 59 tov hold the guide41m guiding position, as shown in Fig. 6. ,This -surface `87 issubstantially kconcentric with the aXis of the pivot 86, but the sideofthe lever is swing backwardly orclockwise, as viewed in Figs. 3, 4,

This' action isshown in dottedlinesinFig. 5. It will be clear that this action forces parts aresojproportioned that the amout brim' is Alowered is,- sufficient tooffset the effect of the drawing down of the brim in the l trimmingoperatiom so' that the kniferunsout at the end `ofthe vtrimming the.curvedV surface 87 af transverse circular groove open 'at `this corner,and mounted in this groove is a cylindrical-pinj92 carrying a flatbarv93'whose free edge 94 -projects through the open side of the slotandalsoproiects beyond the' the brim at the point where 'Y the cut isstarted to a l'position slightly lower 75 thanit `would be if theguide`41 were moved:

When the elementsreach the dot and dash line position 99 shownin Fig.Vv7 with the bar 93 ona radial line 97 passing hroug'h the axis of pivot86,`this radial line ris at substantially V rightvv angles tothe sur-Vface'of meniber59 whichf'is engaged by the free edge .94 ofthe bar 93.5It willthus be clear that a slight further movement of the handleverwill carry bar 93 beyondthis po-v sitionand the pressure ofthe member59'y will swing 'thebar 93 L'against the lower abutment 96 by lrockingit andthe pin 92`in itsgroove,

andas lthis ,movement ofi theV bar will carry its projecting free' 'edge94 from a position youtside the curved surface87f-to a-positiony'substantially on this curve extended, 1as Y Y thefmember59 willfjumpback froml the dot and "dash position 99'( Fig. v7) ,to the dottedposition, yand' 'forces' the guide 41 slightly vlowery than its againstlthe curved surface 87. Thus it will be seen that'themember 93y Vist)lted line positionshown in Fig. 5, which ac- .tion-williforce the hatbrim slightly lower than it wouldif this guide were moved directly tothe full line position (Fig. 5), butV that the swinging of the bar 93 onthe pin 92 to allow the `free edge 94 to swing away from the member 59allows this member to `jump back against the curved surface 87 and v theguide 41 tojump upwardly a small amount from the dotted line 5) tion.'Immediately after this action takes position (Fig.

, place, further movement of the hand lever l the pointed end throughthe hat brim. This causes finger 89, through the cam surface on thelever 78, to advance the trimming knife 67 to the trimming positionforcing slight backward movement ofthe guide 41 is so rapid, however,and the knife is so quickly `advanced after vthis backward movement thatthe knife is in trimming position before the Vhat brim has had a chanceto spring back. f The table carrying the hat brim then immediatelystarts to rotate under mechanismpresently to be described, and thetrimming operation is carried out.

The knife is so mounted that it may be easily and quicklyremovedforsharpening or renewal, andy may be easily and quickly .mounted inposition. The bar 68 carrying 'the knife is suspended on the pin 69carried Vby the block 7 and the spring connecting rod 76 has an openingin which the pin 7 5 is seated. If it is desiredto remove the bar 68,all that is necessary is to remove Vthe Aspring connecting rod 76 fromthe pin 75 by pulling its free end laterally away'from the Abar 68, thenswing the lower end of the bar V68v forwardly outof the notch 66 inguide 41 =when the bar may be slid off its pivot pin 69,-as shown by thedotted lines in Fig. 13.

The bevel gear 114 ismounted to slide on the shaft 112 and kept in mesh with the gear 113 bymeans of a fork 116 carried by the slide 33, but the gear 114 is mountedto rotate with the shaft 112 by a'feather 117 extending through a groovein the gear in the usual manner. i

The main-shaft 112 carries a wormgear 118 meshing with a worm 11.9mounted on a shaft 120, which shaft is driven fromv any suitable sourceof power, as an electric m0- tor 121 having' a belt drive 122 to apulley 123. The shaft is driven from said pulley by a friction clutch124 which is controlled by a lever125 pivoted to the frame at 126. Meansare provided for automatically throwing this iclutch to guiding positionas. thev jaw 41 and trimming knife are moved to their operativepositions, and means is also provided for automatically throwing out theclutch at the end of the trimming operation.

lPivoted to the frame at 127 is a pawl1128 having a hump 129 adapted tobe engaged yby a pin 130 carried by the main drive shaft 112, and thefree end of this pawl is provided with a notch 131 to engage the side ofthe clutch lever 125 to holdsaid lever in the driving position, as shownin Figs. 8 and 9, a spring 132 being providedV tending to move theclutch to the non-driving position, or to throw out the clutch. The pin130 is so located on the shaft 112 that at the completion of thetrimming operation it will engage the hump 129 lifting the notch 131from the clutch lever, and will allowv the spring 132 to throw out theclutch and stop .tl'iema-- chine. `To definitely stop the mechanism,

` however,atV a given point the clutch lever is provided with a. pin 133which is. adapted to move into a curved slot 134 in oneend of a disc 135which is loose. on theshaft .120; but is connected to one end of acoilspringI `136 1 carried in the housing 137 rigidly securedA totheshaft, as by a set screw138,and

This will move the guides 40 and 4:1towards the brim and Valso change ltheir angular position sothat theyare no longer atfright angles to this line but areV at right angles tothe line 179 tangentv to the line; of the ellipse, to which the hat brimis to be trimmed, at the point which is being cut in this position.Inother words thevcombined reciprocating and roclring movement of thelsupport for the brim guides always keeps these guides at substantiallythe same angle tothe curve being' cut in* the brim, so that there is nodistortion or cramping of the brim in the guides and giving a `much`smoother andmore accurate cut. Also this rocking movement keeps thecutting edge of the trimming knife at substantially the sameangle tothesurface of the brim at the cutting point, which gives a uniform cutall the way around the brim. It will also be apparent that the amount ofthis rocking movement will automatically be adjusted for differenteccentricitiesof'the brimy as the position ofthe driving eccentric orcrank 101 is adjusted. Thus if it is desired to Vout a round `brimthecenter of` the eccentric will-beV coincident with `the center ofrotation of the shaft 102'and no rocking movement will be imparted tothe guides.` Underl these conditions :no rocking movementAis requiredbecause there 'is nov movement of the line tangent to the line ofcutting.
